Just received the hoodie in Heather Jet Pack. The color of the actual product does not at all correspond what is shown on the site. I suggest buying this in person, or at least looking at some other sites to verify exactly what you'll receive.
For me the Heather Jet Pack looks quite blue-ish, while the actual item is dark grey.
Otherwise the hoodie is pretty nice, the 2 star rating is for the misleading photos.
